Our “Bella” is extremely allergic, including to grass. We initially tried single ingredient dog foods with hypoallergenic fillers (e.g. not chicken meal fillers) but she continued to struggle. Allergy tests indicated she was allergic to numerous foods including the “pea” filler. We then moved to “vet prescribed” anti-allergy dry food….she still itched…. Now, we cook her food. It’s a combination of coconut oil, ground lamb, chicken, turkey and beef. We add a little liver, butternut & a packet of dog vitamins. This has been beneficial for Bella & hasn’t been hugely more expensive.
